Extreme weather and flooding in Japan

Overview

Japan has faced significant disruptions due to extreme weather, including lightning strikes and heavy rainfall.

In late August, a lightning strike in Kyoto caused equipment malfunctions and the temporary closure of the ‘Sustena Kyoto’ environmental learning facility. Simultaneously, heavy rain in Chiba City flooded underground electrical equipment, resulting in power outages that lasted over a month for some residents and water supply disruptions exceeding one week.

By early September, intense rainfall continued to impact various regions. In Chiba, rainfall exceeding 300mm caused localized flooding and submerged vehicles. In Toyama Prefecture, heavy rains flooded roads, homes, and agricultural fields, while also causing soil erosion. In Hokkaido, authorities in Otaru issued advisories regarding strong winds and potential rain.

On September 7, widespread weather warnings were triggered by heavy rain and the potential for ‘linear precipitation zones’. In Osaka Prefecture, authorities issued strict warnings for landslides and flooding, with some areas facing up to 200mm of rain within 24 hours. A low-pressure system, evolving from Typhoon 24, is moving along the autumn rain front, posing risks of sudden flooding and river overflows in the Shikoku, Kinki, and Tokai regions, as well as intense rainfall in the Kanto region. Additionally, the 8th Regional Coast Guard Headquarters issued maritime safety advisories for the Hokuriku region due to unstable atmospheric conditions.

As conditions persisted on September 7, Kagawa Prefecture issued Level 4 landslide disaster danger warnings for several municipalities, including Marugame, Zentsuji, Kotohira, and Manno. In the Kanto region, rain was expected to expand, with residents in the Izu Islands and Boso Peninsula advised to remain vigilant against landslides following recent record-breaking rainfall. In Yamagata, weather patterns indicated continued rain through the night, while some areas faced extremely heavy rain of up to 60 mm per hour.
